Application filed October 25, 1915. Serial No. 57,896.

fl '0 all IF/L077} it may concern:

Be it known that I, Hn'ozo Kawivrn, subject of the Emperor of Japan, andresident of Seattle, in the county of King and State of Washington, haveinvented certain new binations of parts which will be hereinafterdescribed and particularly pointed out by the claims which terminatethis specification.

The object of my invention is to improve and simplify apparatus of thisclass.

In the accompanying drawings I have shown my device in the form ofconstruction which is now preferred by me.

Figure 1 is a side elevation of my device, parts being broken away tobetter show the operating parts.

Fig. 2 is a top view.

Figs. 3 and 4 are side elevations, partly in section, showing theprincipal operating parts, the position of the parts being different inthe respective figures.

Fig. 5 is an end view of my device, partly broken away, looking towardthe delivery end.

Fig. 6 is an enlarged section of the labeldelivering mechanism. I

Fig. 7 is a sectional view of the same mechanism, taken on the line 77of Fig. 6.

Fig. 8 is another section through the label delivering mechanism takenon line 88 of Fig. 6.

Fig. 9 is an enlarged section through the pivot of the cell segments.

The cans are delivered in stacks consisting of a series of cans placedend to end, these stacks having their axes horizontal. This delivery isby an endless chain 1, having rollers 10, between which the cans 11rest.

From chain 1 the 'cans roll upon an inclined table 2 which has sideguard members 20 supported in a yielding manner, as by pivoting at 21and pressed inwardly by springs 22.

The cans are held during the application of the label, within a cellwithin which theyare rotated to wrap the label about them. As ShL n,this cell is composed of a fixed segment 33, a segment 34 carriedby arm3 which is oivoted at 31, and a segsuliiciently greater diameter thanthe cans to permit the free passage of the label about the can. i

A spring 35 normally holds the outer swinging section 30 in closedposition. A shoulder at 36, limits the closing movement. A link ipivoted to arm 3 at it), has a cam roller upon its other end whichtravels in cam slot 50 of cam disk It also travels in cam slot 41contained in a part of the frame.

As the arm 3 swings down, the weight of can 12 then in the cell, issuliicient to over come spring 35 and open the parts to the positionshown in full lines in Fig. l. Bars relation when the cell is closed, asis shown 16 and has laterally projecting swinging endv 19 positioned toengage link 38 to break or buckle the joint at 39, permitting closure ofthe cell sections 30 and 34-.

Three sets of rubber covered rollers, 6, (30 and 61, are mounted toproject slightly within the circle of the can receiving cell, andconstitute the can supporting and turning means. The rollers 6 aresecured to the main driving shaft 31, upon which the arms 3 are pivoted.Rollers 6, 60 and 61 are idlers. Shaft 31 and rollers 6, turn clockwise,as the machine is shown in Figs. 1, 3 and 4.

Pivoted at 71 upon a post 23 extending from table 2, is an arm 7. Oneend has a. weight 70 secured thereon, the upper surface of the'leverbeing notched, as at 72 to facilitate adjustment of the Weight along thelever. Its other end is pivoted to a link 73 which is pivoted at 40 toarm 3 to which also link 4 is pivoted. Another arm or bar 74 is pivotedto the axis 62 of rollers 61, and carries a pin 76 which enters groove77 of link or bar 7. Bars 74 cairy a trans;

, abar extending across the machine and acts as stop for the cans andwith bar 75, to support a l1ne of cans. The spacing of bars 75 and 78 issuch that as they are swung up they are separated to drop the cansbetween them :and into the opened cell.

ipaste or adhesive tank 89 has one side 85 perforated with holes 86 nearits bottom .ed'ge',w and an extension 87 ofv its bottom beyond {thisperforated side wall.

A, wheel 52 lies above the paste tank and the bunch .eral cans ation'ce.

of labels are placed with the side of the bunch against the outer faceof the perforatedi wall' l and their upper ends bentover wheel p Thenppefr end of the, labelsv rest upon fixed jba s54, between which aremounted 1 feed bldeks =55 to reciprocate "along the bars.

- 80 represents the side walls of the recess or, spafc jewithin whichthe labels are placed.

Ai complete Qinaehinewould preferably have the essential partsduplicated to label sev- A weight 81 having pinslentering inclinedguidinggroovesf S2 is placed on top of each pile. This is odnn ected'byafiexibleqweb 88,

with another, wight,83 which engages the outer surface of theloiver...en d of the pile of labels, lugs dfipins projecting from; plate83 outer grooves 84. These weights hold the ,labels, at one end inposition for feeding, and

"at the otherend' close againstthe perforated plate .jgst.

To the feed block 55 is connected a lever v58, 59, which 1S mounted on atransverse bar 56. To JheloWei vZ'end of this lever'is pivoted a lever.9 which is fulcrum/ed at 91 and has a slotted-end QO embracinga pincarried by the cam roller42.

Transverse bar 56 is mounted in slots 63 in the frame. I As lever 9 isoscillated it swings lever; 58," 5.9,, which first raises {blocks toslightly i'jaise the labels from thegbars 541 the leizer 58 has a finger57 'avhich/then crin-ltatrtp 'with'block 55, preventing further'a'ngularjnovemnt, further movement ofjleyer 58,59 causing a forwardsliding move fnent of block block is of a character which facilitatesen.-

The, upper surface of this can. It then enters the can -re,-'

' The shaft 53 of drum 52 is mounted to slide in slots 51 in framemembers. movements are caused by links 44 which con- Its nect it withlevers 9. This shaft carries a ratchet wheel 45 which is successivelyengaged by fixed pawls 46 and 47 to give it a small, forwardly rotativeimpulse for each reciprocative movement. This movement of the ="drumrelieves the pressure upon the lowermost label'and' assists in feedingit forward.

The upper surfaces of the feed blocks 55 are composed of rubber, or areotherwise niade so as to get good frictional grip on the labels.

Having thus described my. invention, what ,I claim as new, and desire tosecure by Letters Patent of the United States of America, is:

1. In a can labeling machine, in combination, a can receiving cellclosely embracing fthe periphery of the can, rollers projecting withinsaid cell to form carrying supports for the can, means for turning thecan through said rollers and means fol-passing a label within said cellto be wrapped about the can?" 2. A glabeling device for cans having afixed paste reservoir with a perforated wall at one side, means'forsupporting a bunch of labels with their inner face at one end hearingagainst said perforated wall, and means for withdrawing the label whichcontacts said perforated wall and applying it to a can.

3. A labeling device for cans having anadhesive receptacle provided witha perforated side wall, means for supporting a bunch of labels with oneend in vertical position with a side face of the bunch against saidperforated side, means for holdin the upper end of the bunch in curvedposition with the label which contacts with the perforated wall at theconcave side of the curve and means for engaging said inner label towithdraw it from the pile and to apply it to a. can. I

4. In a-can labeling machine, a, can receiving cell adapted to closelyembrace, without gripping, the periphery of the can, means for turningthe can Within said cell, and

means/for feeding a label between the can and the walls of the casincell. 5."
